SolarBest Areas for Solar Panels in the UK
The UK's best areas for solar panels are concentrated in South and South West England, where annual sunshine hours are highest. These areas benefit from longer daylight hours and more direct sunlight, resulting in greater electricity generation and faster payback periods.
